GEORGE W. COREY, OF SAN FRANCISCO, CALIFORNIA.

WINDOW-SCREEN.

To all whom it may concern Be it known that I, GEORGE W. COREY, acitizen of the United States, residing at San Francisco, in the countyof San Francisco and State of California, have invented a new and usefulWindow-Screen, of which the following is a specification.

The invention relatesto lmprovements 1n window screens.

The object of the present invention is to improve the construction ofwindow screens. and to provide a simple, inexpensive and efficientwindow screen, equipped with means for enabling it to be readily appliedto and removed from a window and for also permitting it to bedisconnected at the top from the window and swung outward so that fliesmay be readily driven out of the window.

With these and other objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawings, and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size, and minor details of construction, within the scope ofthe claims, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawings :Figure 1 is a vertical sectional view of a portion of awindow having a screen, constructed in accordance with this invention.Fig. 2 is a front elevation of the window screen. Fig. 3 is a horizontalsectional view of one side of the screen, taken substantially on theline 38 of Fig. 1. Fig. 4 is a detail perspective view of one corner ofthe screen, illustrating the manner of engaging the same with anddisengaging it from a headed fastening device. Fig. 5 is a perspectiveview of one side of the screen, illustrating another form of theinvention. Figs. 6 and 7 are detail perspective views, illustrating twoways of applying the invention to a screen having an ordinary woodenframe.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

In the embodiment of the invention illustrated in Figs. 1 to 4inclusive, 1 designates a window screen, equipped with a frame 2,consisting of bars of rolled metal and provided in its sides at its topand bottom with upper and lower slots 3 and 4, preferably ar-Speeification of Letters Patent.

ranged at a slight inclination and provided at their lower ends withentrances, consisting of relatively short vertical slots 5, connectedwith the lower terminals of the inclined slots 3 and 4 by shorthorizontal slots or branches 6, extending from the relatively shortvertical slots at points intermediate of the ends thereof. The inclinedslots 3 are formed in the. side portions of the rolled side bars ormembers of the screen frame, and the short vertical slots 5 are cut orotherwise formed in the front portion of the roll. These entrance slotspermit the window screen to be readily engaged with and disengaged fromupper and lower nails 7 and 8. The screen 1 is preferably applied to thestrips or beads 9, which form the outer sides or walls of the guides orways, and in applying the screen to the window the former is arrangedbetween the strips or beads 9 and the passages of the upper and lowernails are marked. The screen is then removed and the nails are driven inat the marks previously made, suflicient portions of the nails beingleft projecting to engage with the upper and lower slots of the windowscreen.

In order to enable the screen to be unhooked at the top and swingoutward without disengaging the lower portion of the window screen fromthe window frame, the lower slots 4: are made su'fiiciently long toenable the screen to be raised the distance necessary to bring theentrance of the upper slots opposite the upper nails. The inclination ofthe slots assists in raising the frame from any frictional engagement ofthe upper sash, and at the same time causes a tight engagement or fitbetween the screen and the upper sash when the screen is closed. Theentrance slots of the upper slots will permit the outward movement ofthe upper portion of the screen, and any flies on the latter may bereadily driven out of the window. The upper portion of the window screenmay also be readily reengaged with the upper headed fastening deviceswithout unhooking the bottom of the screen, as it is necessary to liftthe latter a considerable distance in order to disconnect it from theThe lower fastening devices form pivots or pintles for the bottomportion of the window screen when the top of the latter is swungoutwardly or inwardly.

In Fig. 5 of the drawings, the invention is shown applied to a screen10, having a frame 11 constructed of angle metal and provided at thesides with upper and lower slots 12 and 13, arranged at a slightinclination and having horizontal entrance slots 14 and adapted to beengaged with upper and lower headed fastening devices. The lowerinclined slots 13 are longer than the upper slots to permit the screento be disconnected at the top in the manner before explained.

I11 Fig. 6 of the drawings, the invention is shown applied to the woodenframe 15 of a screen 16 by means of a metallic plate 17. The plate 17 isarranged at the lower portion of the screen, and the corresponding plateis applied at the upper portion of the screen, the arrangement of theslots being similar to the slots 12 and 13 of the frame 10. The plate 17is secured by screws 18 in a recess of the wooden frame to arrange it inflush relation with the same, and the wooden frame is provided in rearof or at the inner face of the plate 17 with a recess 19, extendinginwardly from the inner face of the side of the screen frame and adaptedto permit the head of a nail, or other fastening device to be readilyintroduced into and removed from the horizontal slot 20 at the lowerportion of the plate 17 The improvements may, however, be applied to awooden frame without the use of a metallic frame by providing a verticalrecess 21 in the upper and lower portions of the sides of the frame andslotting the outer side wall of the recess to provide a lower transverseentrance portion 22 and an inclined longitudinal portion 28. The slotsshown in both Figs. 6 and 7 are the long slots at the bottom of thescreen, and the upper portions of the screens will be provided withcorresponding short slots to permit the top portion of the screen to bedisengaged and swung outward from the window frame.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

1. In combination with fixed top and bottom horizontal headed fasteningdevices arranged in pairs at opposite sides of a window, of a screenprovided at opposite sides of the top and bottom of its frame with upperand lower slots having entrances at their lower ends to permit theheaded fastening devices to be introduced into the upper and lower slotsfor detachably securing the screen in position, the lower slots beinglonger than the upper slots to permit the screen to be raisedsufliciently to disengage the upper fastening device from the upperslots and to be swung outwardly at the top without disconnecting thelower portion. of

the screen from the window frame, the lower fastening devices formingpintles for the screen when the same is swung outwardly at the top.

2. In combination with fixed top and bottom horizontal headed fasteningdevices arranged in pairs at opposite sides of a window, of a screenprovided at opposite sides of the top and bottom of its frame with upperand lower slots having entrances at their lower ends to permit theheaded fastening devices to be introduced into the upper and lower slotsfor detachably securing the screen in position, said slots beinginclined downwardly and inwardly for causing the screen to wedge itselfagainst the window, and the lower slots being longer than the upperslots to permit the screen to be raised sufliciently to disengage theupper fastening device from the upper slots and to be swung outwardly atthe top without disconnecting the lower portion of the screen from thewindow frame, the lower fastening devices forming pintles for the screenwhen the same is swung outwardly at the top.

3. In combination with fixed upper and lower horizontal headed fasteningdevices arranged in pairs at opposite sides ofa window frame, of ascreen having a frame composed of. bars of rolled sheet metal andprovided in its opposite sides at the top and bottom with upper andlower inclined slots adapted to cause the screen when engaged with thefastening devices to wedge itself against the window, and having lowerentrances located at the lower ends of the slot-s and consisting ofrelatively short upright slots formed in the front portion of the sidesof the screen frame, and short horizontal connecting slots or branchesextending from the lower ends of the inclined slots to the said shortupright slots and connected with the latter at points intermediate ofthe ends thereof, the lower slots being longer than the upper slots topermit the screen to be raised sufficiently to disengage the upperfastening devices from the upper slots and the screen to be swungoutwardly without disconnecting the lower portion of the screen from thelower fastening devices, which form pintles for the screen when thesame, is swung outwardly at the top.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
